Incidental singularity
"I brought this as an extra on a European trip with my young daughter. I found myself going for it more than my usual travel backpack for day trips because of the lack of structure, inherent security, and simplicity. Its black with no structure, so setting it down at a park doesn’t scream “backpack” but more “garbage bag. ” In that spirit, it was a perfect black hole of a pack for the temperature swings of an Iberian spring - water bottles, rain coats, umbrella, sweat shirts, and incidentals, it carried all with ease. If you can add, as I did, a smaller bag for quick-access items across your front, you have an excellent solution for low-volume value in packing. For a week, we each only had a backpack and a carry on roller. Perfect."
